Thank you so much Don. I'll take a look.
--- Post updated 01-22-19 at 07:06 AM ---
I read through that thread Don and while I must admit that I do not exactly follow all of it, it seems to be a bit different than what I am asking here. My problem is not so much dealing with repeated values, but rather getting that "for" loop to work in my awk script.
To isolate the problem further, I am having trouble getting $2 in File 1 to precisely match a string in File 2 on lines that begin with "Lexeme" (~/ ^L/) giving me fits. I have highlighted the two lines of code in both of the example *.awk scripts with red font. In principle something similar to awk 'FNR==NR{B[$2]; next}{for (b in B) if ($0 ~b) print} ' File[12] should do the trick, but relative to this particular issue: (A) I'm having difficulty getting something like that to work in my script; and (B) this does not produce exact matches, but rather treats the values of $2 in File 1 as strings (rather than say $2 ~/^pattern$/). Thus for the line in File 1 that reads PS005,007 ML I'll get matches such as MLL> MLT> TQML, etc.
Hopefully that hones in on my particular impasse that I'm experiencing.

SPLIT(1) General Commands Manual SPLIT(1)
NAME
split - split a file into pieces
SYNOPSIS
split [ option ... ] [ file ]
DESCRIPTION
Split reads file (standard input by default) and writes it in pieces of 1000 lines per output file. The names of the output files are xaa,
xab, and so on to xzz. The options are
-n n Split into n-line pieces.
-l n Synonym for -n n, a nod to Unix's syntax.
-e expression
File divisions occur at each line that matches a regular expression; see regexp(7). Multiple -e options may appear. If a subex-
pression of expression is contained in parentheses (...), the output file name is the portion of the line which matches the subex-
pression.
-f stem
Use stem instead of x in output file names.
-s suffix
Append suffix to names identified under -e.
-x Exclude the matched input line from the output file.
-i Ignore case in option -e; force output file names (excluding the suffix) to lower case.
